Combine options for HJsplit and JD unrar
|Target version:||040 - FarfarAway|
Combine these two operations into one command, Process archive.
This would remove user confusion, eliminate a second-level menu, and take advantage of 7-zip's ability to undo splits.
This is especially important for deep extraction, where there can be splits and compression at different levels.
Relates to expected change in JD unrar to use 7-zip or the 7za library.
Forum thread: http://board.jdownloader.org/showthread.php?t=13113 assumes this change.
